Our HMIS® labels serve as a primary way to comply with OSHA's Hazard Communication Standard and have an easy-to-understand rating system to inform employees about the potential hazards of chemicals they might encounter in their workplace. Fill in these 1 x 2-in., high-gloss, thermal-imprintable, paper right to know labels with the Chemical Identity; the Health, Flammability, Physical Hazard ratings and the Personal Protection letter code for chemicals you use regularly. They are sold in rolls of 500.
